Question

Wanda manages an application that fluctuates in usage quite a bit. Sometimes it uses quite a few servers with lots of memory and CPU while other times it only uses a couple of servers with minimal CPU and memory allocated to them. She doesn't have to manually make changes as the system has the ability to increase or decrease those resources on its own. Which of the following terms describes that capability?
a. Reliability
b. Scalability
c. Elasticity
d. Availability

Answer 1

Answer:

c. Elasticity

Explanation:

When referring to Cloud Servers this capability is known as Elasticity. It basically describes how able and efficient a server is to automatically implement resources and remove resources in order meet the specific amount of demand at any given moment. Many times a server will not have much demand but will still have all the resources being used by the server. Being able to remove these unused resources so that they are available for other usage is what makes the servers elastic.
